KUDOS
attendees = 100
people who paid the fees in full = x

0.1x = who paid the fee in full but did not do 2 weeks in advance.
0.9x = people who paid the fee in full and paid atleast 2 weeks in advance = 72

x= 72/0.9 = 80

thus people who paid fee and not 2 weeks in advance = 0.1*80 = 8
so

Fee !Fee
2 weeks advance 72 20 92
! 2 week advance 8 0 8

total = 100

so 92%

Looks like this question is not complete. The required percent cannot be determined with given data. The answer can range from 72% to 92%. Could you please confirm?

My take :

0.72A -> At least 2 weeks in advance and paid conference fee in full.

FA -> Paid the conference fee in full

0.10FA -> Not 2 weeks in advance paid but conference fee in full

=> 0.90FA -> 2 Weeks in advance and paid the conference fee in full

0.90FA = 0.72A

FA/A = 72/90 * 100

= 80%

Answer - D

Exactly
we dont have any bifurcation of people who did not pay the full fee (how many registered in 2 week advance and how many did not)

without knowing that we can't reach the desired answer that how many registered in 2 weeks advance
it could be 72% +0% (minimum) to 72% + 20% (maximum)

please clarify :? :?

@amit2k9,

how can you say that people who didnt register two weeks in advance and not paid in full =0 ? Did you assume that?

attendees = 100
people who paid the fees in full = x

0.1x = who paid the fee in full but did not do 2 weeks in advance.
0.9x = people who paid the fee in full and paid atleast 2 weeks in advance = 72

x= 72/0.9 = 80

thus people who paid fee and not 2 weeks in advance = 0.1*80 = 8
so

Fee !Fee
2 weeks advance 72 20 92
! 2 week advance 8 0 8

total = 100

so 92%

yes between 72 and 92%, so answer could be any of C, D and E.
